Urea → Melamine cyanurate

Participants

Reaction Steps

The procedures of Example 4 were repeated except that 9 g of prilled urea (product of Mitsui Toatsu Chemicals, Inc.; melting point: 132° C.; average particle size: 1 mm) were reacted, in place of the cyanuric acid, with 4.5 g of the melamine at 300° C. As a result, melamine cyanurate was obtained in the form of a block. The yield and purity were 93% and 87.2%, respectively.
